thanks! I do not use any suppliments in either of my reefs. I just rely on good ol' fashion water changes to keep my Ph, CA and ALK where they need to be and to replenish trace elements.do you use something like calcium or reef supplement to grow those beautiful coral?
Not really, but it depends on what you want to keep your Calcium at. I do not have a problem keeping mine between 430-450.so... calcium liquid is necessary for the tank if i want to keep corals?
